ACETiYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 594,849, dated December '7, 1897.

Application filed September 3, 1896.` Serial No. 604,719. (No model.)

To all whom it, may concern.-

Be it known that I, GIANNI BETTINI, asubject of the King of Italy, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Gas-Generators, of which the following is a specification. My invention has reference to gas-generators in which the evolution of the gas results from the contact of a liquid with a'solid, leaving a solid residue, and it has special reference to generatorsof acetylene gas. It has for its object to render the process of separating the gas a continuous process and generally to simplify and perfectthe mechanism.

It consists of the mechanisms herein set out. In the accompanying drawings, which form a part hereof, Figure l is a View, partly in section, of an apparatus embodying my invention.. Fig. 2 is a view, partly in section, taken on a line at right angles to the plane f section of Fig. l. Fig. 3 is a diagrammatic view of my apparatus set up with a storage- Kss supply and a gasometer in connection therewith. Figs. 4 and 5 are details illustrating certain devices for locking movable parts from being operated at a Wrong time. 6 is a detail illustrating a check-valve for the discharge-pipes.

D is the main body of the generator. It is made of suitable material and gas-tight and is adapted at its upper end to receive the generated gas and to discharge the same through delivery-pipe G and at its lower end 'r to receive the solid residue, from which said residuring the gas-generating process and at the same time to permit the contact of the liquid ingredient with the solid ingredient, and in order to provide accessfor the purposes of Fig.

said contact I preferably make the support B in the form of ar grate with bars and intervening spaces or slots, as shown, andI preferably arrange it so that when performing its supporting functions it is normally sloping or inclined downward away from the opening a. This supporting-grate B is movable in order to accomplish lthe removal therefrom of the solid residue left by the operation of the generation of the gas, and to that end it is pivoted centrally and connected through an airtight bearing-box to the external mechanism b, which is a handle-bar by which the grate B may be shaken or turned. To more reliably hold the grate B in position during the gas-generating operation the handle-bar b may at such time be locked, as by the chainl b. The bar which connects the grate B with the handle b passes through a gas-tight bearing-box M, which has a flexible part consisting of suitable bellows-like construction of gas-tight fabric or rubber, which permits the necessary motion of the parts in shaking or turning the grate B without permitting the escape of gas from the generator or the entrance of air into the generator.

A is the feed-box or supply-receptacle for the calcium carbid or other solid ingredient. It opens at a into the generator above the position of the support B. A gate or port C closes or opens the inlet of. To that end it slides vertically in slideways c c and is controlled by a rod operated by suitable mechanism J, exterior to the generator, the connecting-rod passing througha gas-tight bearing-box M' in the generator. bearing-box permits the necessary motion of the part .I required to close or open the gate C without permitting the escape of gas from or the access of air to the generator. n l

It is important that the supporting grate B should never be turned from its supporting position except when the gate C is down and the inlet ct thereby closed. To that end the supporting-grate B is locked in its supporting position by the trip E wheneverl the said support is returned to its supporting position and so long as the gate C is wholly or partly open. When, however, the gate C is lowered and the inlet a thereby wholly closed, an arm el on the gate C strikes against the This gas-tight` trip E and moves it so that it no longer locks the grate Bin supporting position. a y able form of catch and trip might be used for this purpose. It is also important that the gate C should never be raised and the inlet a thereby opened unless the grate B is in its supporting position. To that end the device orcatch His provided. This catches the arm d of the gate C whenever the latter is lowered and locks it in that position unless'the grate B is in its supporting position, in which case the latch is forced back by the grate out of locking position. Any suitable locking device might be substituted for the special latch Il.

T is a perforated metallic shield or screen which I preferably use to prevent the solid ingredient from piling up into the upper part of the generator. It is shown in Fig. 2, b ut is broken away in Fig.`l. a F is a slicing or stirring rod for stirring and mixing the solid ingredient on the support B during the operation of gas-generation and for shaking and sifting the solid residue through the grate B without moving the latter. This slicing bar or rod is pivoted or suit-ably mounted in the wall of the generator and is connected through a gas-tight bearing-box with the external operating handle F. rlhe gas-tight bearing-box ismarked M2 in the drawings. It permits of the universal manipulation oi' the slicing rod F Without permitting the escape of the gas from or the` access of air to the generator. The bearingboxes M and M2 should also be liquid-tight. The receptacle A has at the top a suitable port or manhole S', constructed' to be closed air-tight and gastight. It has also a gasdischarge pipe G, connecting with the gasdischarge pipe G, for the removal of any accidentally-formed gas that may accumulate in the top of the receptacle A. The generator D and the feed-receptacle A may also have the gas-test burners n n at the top. The liquid-inlet g is supplied from the open liquid stand-pipe O, which has a suitable valve q at the bottom. The generator has an escape-cock L for drawing off the liquid when desired. The generated gas passes through the discharge-pipe G into any suitable gasometer or storageftank Z or into a series of same. The'gas-discharge pipes G Gf have a ball check-valve or other suitable valve P to freely permit the passage of the'gasV upward and outward, but to prevent its passage backward.

The operation of the device is as follows: rlfhe receptacle A being filled with the solid ingredient while the gate C is closed, and the generator being closed up and the grate B being turned into its supporting position, the gate C is opened and the solid ingredient allowed to enter and cover the support B. A

. suitable quantity of water isthen introduced into the water-supply or stand pipe O, the

valve qis opened,and the water rises inthe 'gen` erator until it comes in contact with the solid Any suitaccumulates, displacing the water.

ingredient on the support B, when the generation of gas begins. The quantity of water in the pipe O should be regulated in such a way that when the evolution of gas is too great the level of the water in the genera tor will be forced down by the pressure and the generation of the gas be thereby automatically regulated. The amount of pressure of the gas may be regulated by the amount of water kept in the stand-pipe O. The solid residue of the gas-generating process will to some extent fall through the openings of the support B. Whenever necessary or desirable, the slicing or agitating rod F may be manipulated to expedite or accomplish this sifting of the solid residue through the openings of the support B. The gate C may be more or less opened or closed as experience may dictate. lVhenever desirable,the gate C may be wholly closed and the support B` may be turned, thereby entirely. dumping the solid residue that may cling thereto` that would otherwise remain thereon and interfere with the further generation` of gas. This solid residue falls to the bottom of the generator, where it gradually After such dumping of the solid residue the gate C is again opened, and the gas-generating process continues. l This may be kept up in- `definitely long wit-hout at any time substantiall y interrupting the gas-generating process until the accumulation of the solid residue in the bottom of the generator threatens to iill up the inlet g. rFhat solid residue is then removed in the following manner: The gate O having been closed and the grate B dumped the valve q is closed. The water remaining in the bottom of thegenerator and on top of the solid residue is drawnoff by the faucet L. The

h door Sis then opened and the solid residue is i raked or shoveled out, after which the door S is closed and the process resumed.

Fig. 3 shows in diagram a preferred arrangement of the feed-receptacle A as a storagevault and outside of the wall of the house in combination with the generator D` in the cellar of the house against the wall. It shows rlhe generator here described is absolutely safe from explosion, inasmuch as any tendency in that direction would be prevented by the open standpipe O. The process, moreover, is practically continnous so long as the solid residue does not haveto be removed from the bottom of the generator, and the receptacle for the same in the bottom of the generator may be made as large as desired. All of the mani-pulation required is exterior to the generator and may be accomplished without the escape of gas intothe surrounding air and; without any dangerous ad mixture of air with gas within the apparatus.

Many modiiicationsmay of course be made in the details of the mechanism shown without departing from the spirit of theinvention.

What I claim as new, and desire to secure by Letters. Patent, is-
